WTB - bottom part of Hovabator, 1998-2004 model

[exop]

Hi, I'm looking for a styrofoam hovabator bottom to complete my hovabator!

The piece I need has square corners - not like the new hovabators, which are all rounded at the corners.

Also, it needs to fit onto a plastic liner. (Very old hovabators - like from the eighties - don't have the liner). I have the plastic liner already, I just need the styrofoam that fits it.

Any part made during the years 1998 - 2004 should work great!

Here's a picture of the hovabator I'm trying to rebuild:

Here's the plastic liner for this model of hovabator, which I still have:

Thanks for your help!!
